The electro-oxidation of the mixture of formaldehyde and 2-propanol on gold (100) and (111) single crystal planes in alkaline medium
Elektrooksidacija smeše formaldehida i 2-propanola na monokristalima zlata orijentacije (100) i (111) u alkalnoj sredini
Апстракт
The effect of formaldehyde on the oxidation of 2-propanol and vice versa on gold single crystal planes (100 and 111) was studied. An activating effect in the reaction of the simultaneous oxidation of 2-propanol and formaldehyde was obtained on a gold (100) plane. In the case of a gold (111) electrode, the activation effect was not obtained. It was concluded that the adsorption of formaldehyde on the electrode surface prevents the adsorption of poisoning species formed during the electro-oxidation of 2-propanol on the Au(100) plane, while this is not the case on the Au(111) plane. The different behavior is caused by the difference in the symmetry of the surface atoms of these two Au single crystal planes. .
Ispitivan je uticaj formaldehida na oksidaciju 2-propanola i vice versa na monokristalima zlata orijentacija (100) i (111). U reakciji simultane oksidacije 2-propanola i formaldehida na monokristalu zlata orijentacije (100) dobijen je aktivacioni efekat. Ovaj efekat nije dobijen na elektrodi od zlata orijentacije (111). Zaključeno je da prisustvo adsorbovanog formaldehida onemogućava adsorpciju čvrsto vezanih intermedijera formiranih tokom elektrooksidacije 2-propanola, koji se ponašaju kao otrovi za elektrodu, na ravni (100). Ovo nije slučaj na ravni (111). Različito ponašanje je uzrokovano razlikama u simetriji i energijama površinskih atoma na ove dve monokristalne ravni. .
